Technical - Materials
Often the most difficult decision to be made is the selection of material, because it involves the most cost-sensitive of compromises

Material choice is directly related to service life and the longer the required life the more expensive will be the materials. The cost of these materials
also must be considered as an equation of initial investment versus maintenance costs and eventual replacement

Because service conditions for Unitray can vary over an enormously wide range, even within a single installation, it is impossible to write down any
hard and fast rules on the subject of corrosion and expected lifespan

The following may be considered a guide as to what can be expected from the various materials and finishes currently available for our cable support
systems

Galvabond
Galvabond, also known as Pre-Galvanised, is the most commonly used product finish for internal installations.The Z275 impregnated coating shows
good resistance to corrosion in protected environments,and is cost effective against all other coating options

Aluminium
Aluminium is also a popular choice of material for Unitray. Most frequently it is selected because of its excellent
performance in marine environments such as is found on wharves, coal loaders or similar Port Facilities where salt spray or salt laden
atmosphere is present. Another reason for using aluminium is that it offers a long maintenance free life which is important in cases
where access for future painting or repairs may be costly and difficult

For any given load class or capacity, aluminium Unitray is more expensive than their galvanised steel counterparts. Aluminium
Unitray can also be expected to have a greater deflection than an equivalent steel system. On the other hand, they are lighter, more
readily handled and are easy to work with, resulting in faster installation and therefore lower installation cost

Hot-Dip Galvanized Steel
Hot-dipped galvanised steel (after fabrication) is a common selection, as it is economical to purchase and
suitable for most conditions of outdoor exposure. For indoor applications, or anywhere that is essentially free from moisture, galvanised
Unitray can be considered to have an indefinite life. That is, they should last as long as the plant, building, cabling or equipment which
they service

On a typical industrial or processing plant installation, exposed to weather, moisture and airborne industrial pollution, a basic life
of approximately ten years can be expected. This is not to say that the Unitray will be completely corroded in that time but it is the
probable life of the corrosion protection finish. Beyond that time, rapid decay can be expected and maintenance costs will increase
substantially in order to keep the Unitray serviceable

If installed near the coast, the effect of salt laden air may shorten the expected life. Also galvanising is sensitive to some chemicals, especially
sulphurous compounds, which may be intrinsic to plant operations where the Unitray is installed. Correspondingly, a longer life will be expected in
lighter industrial situations and if drier conditions exist

Stainless Steel
Stainless Steel is sometimes considered as a material for Unitray, usually where extremely high corrosion
resistance, coupled with difficulty of servicing after installation and a high degree of reliability are essential requirements. An off-shore
oil drilling platform may be one example where these conditions exist
